“A stressed-out and traumatized father can leave scars in his children. New research suggests this happens because sperm “learn” paternal experiences via a mysterious mode of intercellular communication in which small blebs break off one cell and fuse with another.

Carrying proteins, lipids and nucleic acids, these particles ejected from a cell act like a postal system that extends to all parts of the body, releasing little packages known as extracellular vesicles. Their contents seem carefully chosen. “The cargo inside the vesicle determines not just where it came from but where it’s going and what it’s doing when it gets there,” says Tracy Bale, a neurobiologist at the University of Maryland School of Medicine.

Preliminary research Bale and others, announced this week at the annual meeting of the Society for Neuroscience in San Diego, shows how extracellular vesicles can regulate brain circuits and help diagnose neurodegenerative diseases—in addition to altering sperm to disrupt the brain health of resulting offspring.”

"CNN dropped the lawsuit when the White House agreed to allow Acosta to regain access, and instituted new guidelines for press conferences. As with of Trump’s other pokes at the Constitution, this one got at the heart of core democratic norms."

"With lots of money, one can buy special protective technology, hire expensive private guard labor, move to a different place, or simply rebuild one's property if it gets destroyed. But that doesn't mean you will be invulnerable."

"In general, progress has brought about unprecedented prosperity while also making it easier to do harm. But between two kinds of outcomes — gains in well-being and gains in destructive capacity — the beneficial ones have largely won out."

"In 1930, John Maynard Keynes predicted that, by the end of the century, technology would have become so far advanced that developed economies would have a 15-hour workweek. So how did we get to our current state...?"

"Thanksgiving is the perfect time for you to give it a try. Before the big day, practice discussing a couple of difficult topics with Angry Uncle Bot, a chat program created to help teach you the techniques."

"Under the right conditions, proteins can survive for millions of years. In recent years, proteomic studies of art works and archeological remains have yielded biological information of startling clarity..."
